Improvement in cotton-scrapers

GEORGE IV. BEARD, OF GRENADA, MISSISSIPPI.

IMPOVEMENT IN COTTON-SCRAPERS.

Specification forming part of Letters Patent No. 158,457, dated January5, 1875; application filed November 16, 1874.

To all whom it may concern:

Be it known that I, GEORGE W. BEARD, of the city and county of Grenadaand State of Mississippi, have invented a new and ImprovedGotton-Scraper; and I do hereby declare that the following is a full,clear, and exact description ofthe same, reference being had to theaccompanying drawing, forming a part of this specilication, in which--Figure l is a side elevation; Fig. 2, a plan view.

The invention relates to the shape and mode of attaching Scrapers to aturn-plow; and consists in making the forward or cutting edge of thescraper come to a point at the middle of front, and form an angle with'the stopping and retreating upper and lower edges; also, in the relativearrangement of the scraper with respect to the plow, so that what theformer shaves from the sides of row will be transferred to the share andmoldboard of plow, so as to be turned with the ordinary furrow into themiddle of space betweenmows.

A represents a plow-beam, provided with handles B-and an ordinarybar-share plow, C. D is my improved scraper, which is made concave onits working-face, and has two cutting-edges, d d, that come to a pointat d1, thelltter'forming the vertex of an angle, d cl i By thisconstruction I secure a slanting cut, while the grass and roots cannotlodge on the lance-shaped blade.

It will be observed that the edge d2 of scraper is shaped to correspondwith the front curve c2 of plow, and to stand a little farther forward,so that the dirt from the concavity of scraper will readily and easilybe passed onto the share and mold-board of plow. I secure this relativeposition to the scraper and plow by fastening the scraper to the beam bythe bent bar E, which is riveted to the former, and attached to thelatter by a yoke, wedge, and clamp-screw, or other suitable fastening.

This improvement is on a scraper patented by me August 9, 1859, in whichI have since discovered several serious defects that are thought toberemedied by this invention.

I adhered to the attachment principle, which I conceive to be the trueone, and the only one by which a scraper may be obtained at once, cheap,and good.

I found that my scraper of 1859 was defective in the shape of thescraper-blade, and in the mode ofV attachment. The cutting-edge made asquare out through the ground, which Acaused grass, roots, dead grass,&c., to lodge upon the edge, and clog the plow. This is obviated bymaking the front edge of my blade D lance-shaped, so as to make aslanting cut. Then again there was a serious defect in the mode ofattaching it to the plow. This was done by lapping the scraper-bladeover the plow-share, and bolting it through holes, the edge of thescraper and the point of the plow forming an angle, into which wereinevitably caught all the roots, grass,

,860. The plow thus required to be stopped every few rods, in order tohave the obstacles removed.

In the present mode of attaching a scraper I overcome this diflculty byriveting the crooked bar to the scraper and attaching it to the beam.Then, by setting the scraper about one inch away from, and slightlyforat thepoint passing in a continuous slice over the scraper andplow-share and ot't' into the middle space between the rows.

The large volume of earth thus taken up and turned over is of greatadvantage in thoroughly covering up foul middlesi I am aware of the Yost& Taylor scraper attachments, but they lack the shape and mode ofarranging, with respect to the plow, to that 0270i plow, theV saidscraper andl plow that I deem essential 413o success with the beingsecured to separate standards, and. re1- scraper-plow. atively arranged,as and for tlie purpose speci- Havn g thus described my invention, whatlied.

I claim as new s- GEORGE W. BEARD.

The combination, with bar-share plow C, Vitnessos:
